Description

Technical Field

[0001] This utility model relates to the field of marine engineering equipment technology, specifically to a marine telescopic high-strength drum. Background Technology

[0002] Offshore drums are key equipment in marine engineering used for deploying and retrieving cables, ropes, or pipes, and are widely used in ship mooring, lifting equipment, and subsea pipeline laying. They are typically wound with steel wire rope or fiber rope, the specific choice depending on the application requirements. The design of offshore drums must meet requirements for strength and corrosion resistance to ensure stability and safety in complex marine environments.

[0003] Existing marine engineering drums have a relatively fixed structure and cannot adjust their length according to the amount of steel rope wound. When the drum is too short, its internal capacity cannot meet the winding requirements of long steel ropes. When the drum is too long, it is inconvenient to form dense steel rope loops during winding. In addition, due to the large tension of steel ropes in marine operations, the drum needs to have high structural strength. Therefore, we propose a marine telescopic high-strength drum. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a marine telescopic high-strength drum. This drum features a reliable telescopic adjustment unit that effectively adjusts its length to meet the winding requirements of steel ropes of different lengths. A circumferential array of locking sliding rods on the inner wall provides effective support between the telescopic inner drum and the sliding inner core, improving the drum's radial load-bearing capacity and thus ensuring its structural strength. It also has a reliable transmission support unit that effectively supports the drum body. The separate design of the upper and lower frames allows for effective power transmission and disconnection, facilitating drum length adjustment. Furthermore, the bottom frame can move accordingly with changes in drum length, maintaining effective support at all times. This invention effectively solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine telescopic high-strength drum, comprising a base, a telescopic adjustment unit, and a transmission support unit;

[0006] Base: It has a horizontal sliding groove structure and fixed feet are fixedly connected to the left and right sides on the outside;

[0007] Telescopic adjustment unit: includes a main cylinder, an inner partition, a telescopic inner cylinder, an end baffle, a connecting block, a threaded rod, and a wheel. The main cylinder is horizontally positioned above the base. An inner partition is fixedly connected to the middle of the main cylinder. A telescopic inner cylinder is slidably connected to the left and right sides of the inner partition inside the main cylinder. The outward-facing end of the telescopic inner cylinder is fixedly connected to the center of the inward-facing side of the end baffle. A cylindrical connecting block is fixedly connected to the center of the outward-facing side of the end baffle. The threaded rod passes horizontally through the end baffle and is threadedly connected to the center of the connecting block. The outward-facing end of the threaded rod is fixedly connected to the center of the wheel.

[0008] Transmission support unit: installed on the lower side of the left and right ends of the main cylinder.

[0009] The end baffle is used to lock and limit the steel rope wound on the outside of the drum. When the length of the drum needs to be increased, the threaded rod can be driven to rotate into the main drum by rotating the wheel. When the inner end of the threaded rod is against the inner partition on the middle side of the main drum, a reverse thrust can be applied to the connecting block. The connecting block drives the end baffle and the telescopic inner cylinder to slide outward. The telescopic inner cylinders on both sides extend from the end of the main drum, thereby increasing the length of the drum and allowing more steel wire rope to be wound.

[0010] Furthermore, the telescopic adjustment unit also includes a sliding inner core, a snap-fit ​​sliding rod, and an insertion hole. A sliding inner core is fixedly connected to the center of each of the left and right sides of the inner partition. A transverse sliding groove is formed on the outer circumference of the sliding inner core, with the vertical cross-section of the groove being a trapezoidal structure with the opening facing outwards. A snap-fit ​​sliding rod is fixedly connected to the inner wall of the telescopic inner cylinder in a circumferential array, the number of which matches the number of sliding grooves on the outer side of the sliding inner core. The snap-fit ​​sliding rod is engaged and slidably connected in the sliding groove on the outer side of the sliding inner core. A transverse insertion hole is formed through the interior of the sliding inner core along its central axis, and the threaded rod is inserted into the insertion hole. The snap-fit ​​effect between the snap-fit ​​sliding rod and the sliding inner core prevents the telescopic inner cylinder from rotating, allowing it to slide only laterally along the sliding inner core. Furthermore, the snap-fit ​​sliding rods on the inner wall provide effective support between the telescopic inner cylinder and the sliding inner core, improving the radial load-bearing capacity of the drum and thus effectively ensuring the structural strength of the drum.

[0011] Furthermore, the transmission support unit includes a support frame, a bearing, gear one, gear two, a sliding support, and a hydraulic cylinder. The end baffle is circular, and a support frame is fixedly installed on its outer side. A bearing is installed and fixed inside the support frame. Half of the connecting block is fixedly connected to the inner ring side of the bearing, and the other half of the connecting block extends from the inner ring side of the bearing. Gear one is fixedly connected to the outer side of this part. Gear two is rotatably connected to the lower part of the side of the support frame. A sliding support is vertically provided on the lower side of each support frame. A chamfered structure is provided at the position where the sliding support connects with the support frame. A hydraulic cylinder is embedded in the middle of the interior of the sliding support. The telescopic end of the hydraulic cylinder faces upward and is fixedly connected inside the support frame. Gear one and gear two are always meshed. The support bracket is used to support the connecting block at the end of the drum. By setting bearings, the connecting block can be rotated while maintaining the support effect. When the connecting block rotates, it can drive the telescopic inner drum to rotate. Through the snap-fit ​​structure inside the telescopic inner drum, the sliding inner core and the main drum body can rotate synchronously with the telescopic inner drum. The hydraulic cylinder at the upper end of the sliding support is used to drive the support bracket to lift and lower, thereby realizing the transmission and disconnection of power. When the support bracket is raised and separated from the sliding support, the power is cut off to facilitate the adjustment of the drum length.

[0012] Furthermore, the transmission support unit also includes auxiliary slide rods, a motor support, a motor, and gear three. Two auxiliary slide rods are fixedly connected to the lower end of the support frame, and the lower ends of the auxiliary slide rods are slidably connected to the upper interior of the sliding support. A motor support is fixedly connected to the outer side of the sliding support, and a motor is mounted on the upper side of the motor support. The output shaft of the motor faces inwards, and gear three is fixedly connected to the end of the output shaft. The auxiliary slide rods prevent the hydraulic cylinder shaft from bearing excessive lateral thrust. The motor support is used to mount the motor. When the support frame and the sliding support are combined, gear three at the end of the motor meshes with gear two, enabling power transmission through the gear set. The motor drives the connecting block and the drum to rotate through the gear set.

[0013] Furthermore, the transmission support unit also includes threaded holes and fixing bolts. Two threaded holes are provided at the engagement points of the lower end of the support frame and the upper end of the sliding support, and fixing bolts are installed inside the threaded holes. When the support frame and the sliding support are combined, tightening the fixing bolts vertically limits and fixes the shaft of the fixing bolts to the support frame and the sliding support, thereby tightly fixing the two separate frame components together to ensure the overall structural stability of the frame.

[0014] Furthermore, it also includes a partition block and a limiting slide rod. A partition block is fixedly connected to the middle of the inner side of the base, and a transverse limiting slide rod is fixedly connected inside the base. The left and right ends of the limiting slide rod are slidably connected to the lower ends of the left and right sliding supports, respectively. The partition block is used to divide the two sliding supports, and the limiting slide rod can limit the two sliding supports inside the base, allowing them to slide only laterally, thus enabling the adjustment of the support position as the drum extends and retracts.

[0016] 1. It has a reliable telescopic adjustment unit, which can effectively adjust the length of the drum to meet the winding requirements of steel ropes of different lengths.

The connecting block drives the end baffle and the telescopic inner drum to slide outward. The telescopic inner drums on both sides extend from the ends of the main drum body, thereby increasing the length of the drum and allowing more steel wire rope to be wound. Through the circumferential array of snap-fit ​​sliding rods on the inner wall, effective support can be provided between the telescopic inner drum and the sliding inner core, improving the radial load-bearing effect of the drum and thus effectively ensuring the structural strength of the drum.

[0017] 2. It has a reliable transmission support unit that can effectively support the drum. The separate design of the upper and lower frames can effectively realize the transmission and disconnection of power, which facilitates the adjustment of the drum length.

[0018] 3. This utility model has a reliable telescopic adjustment unit, which can effectively adjust the length of the drum to meet the winding requirements of steel ropes of different lengths. When the length of the drum needs to be increased, by rotating the wheel, the threaded rod can be driven to rotate into the main drum.

The connecting block drives the end baffle and the telescopic inner cylinder to slide outward. The telescopic inner cylinders on both sides extend from the ends of the main drum, thereby increasing the length of the drum and allowing more steel wire rope to be wound. Through the circumferential array of snap-fit ​​sliding rods on the inner wall, effective support can be provided between the telescopic inner cylinder and the sliding inner core, improving the radial load-bearing effect of the drum and thus effectively ensuring the structural strength of the drum.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This embodiment provides a technical solution: a marine telescopic high-strength drum, including a base 1, a telescopic adjustment unit 3 and a transmission support unit 4;

[0029] Base 1: It has a horizontal sliding groove structure and fixed feet 2 are fixedly connected to the left and right sides on the outside;

[0030] Telescopic adjustment unit 3: includes main cylinder 31, inner partition 32, telescopic inner cylinder 33, end baffle 37, connecting block 38, threaded rod 39 and wheel 310. The main cylinder 31 is horizontally arranged above the base 1. The inner partition 32 is fixedly connected to the middle position inside the main cylinder 31. A telescopic inner cylinder 33 is slidably connected to the left and right sides of the inner partition 32 inside the main cylinder 31. The outward end of the telescopic inner cylinder 33 is fixedly connected to the center position of the inward side of the end baffle 37. A cylindrical connecting block 38 is fixedly connected to the center position of the outward side of the end baffle 37. The threaded rod 39 passes horizontally through the end baffle 37 and is threadedly connected to the center position of the connecting block 38. The outward end of the threaded rod 39 is fixedly connected to the center position of the wheel 310.

[0031] Transmission support unit 4: installed on the lower side of the left and right ends of the main cylinder 31.

[0032] The end baffle 37 is used to lock and limit the steel rope wound on the outside of the drum. When it is necessary to increase the length of the drum, the threaded rod 39 can be driven to screw into the main drum 31 by rotating the wheel 310. When the inner end of the threaded rod 39 is against the inner partition 32 on the middle side of the main drum 31, a reverse thrust can be applied to the connecting block 38. The connecting block 38 drives the end baffle 37 and the telescopic inner cylinder 33 to slide outward. The telescopic inner cylinders 33 on both sides extend from the end of the main drum 31, thereby increasing the length of the drum and allowing more steel wire rope to be wound.

[0033] The telescopic adjustment unit 3 also includes a sliding inner core 34, a snap-fit ​​sliding rod 35, and an insertion hole 36. A sliding inner core 34 is fixedly connected to the center position on both sides of the inner partition 32. A horizontal sliding groove is formed on the outer circumference of the sliding inner core 34. The vertical cross section of the sliding groove is a trapezoidal structure with the opening facing outward. A snap-fit ​​sliding rod 35 is fixedly connected on the inner wall of the telescopic inner cylinder 33 in a circular array. The number of snap-fit ​​sliding rods 35 is the same as the number of sliding grooves on the outer side of the sliding inner core 34. The snap-fit ​​sliding rods 35 are snapped and slidably connected in the sliding grooves on the outer side of the sliding inner core 34. A horizontal insertion hole 36 is formed through the interior of the sliding inner core 34 along the central axis. A threaded rod 39 is inserted into the interior of the insertion hole 36. The snap-fit ​​effect between the snap-fit ​​slide rod 35 and the sliding inner core 34 can prevent the telescopic inner cylinder 33 from rotating, allowing it to slide laterally only along the sliding inner core 34; and the snap-fit ​​slide rod 35 arranged in a circumferential array on the inner wall can provide effective support between the telescopic inner cylinder 33 and the sliding inner core 34, improving the radial load-bearing effect of the drum, thereby effectively ensuring the structural strength of the drum.

[0034] The transmission support unit 4 includes a support frame 41, a bearing 42, a first gear 43, a second gear 44, a sliding support 45, and a hydraulic cylinder 46. The end baffle 37 has a circular structure, and the support frame 41 is fixedly installed on its outer side. The bearing 42 is installed and fixed inside the support frame 41. Half of the connecting block 38 is fixedly connected to the inner ring side of the bearing 42, and the other half of the connecting block 38 extends from the inner ring side of the bearing 42. The first gear 43 is fixedly connected to the outer side of this part. The second gear 44 is rotatably connected to the lower side of the support frame 41. A sliding support 45 is vertically provided on the lower side of each support frame 41. The sliding support 45 has a chamfered structure at the position where it connects with the support frame 41. The hydraulic cylinder 46 is embedded in the middle position inside the sliding support 45. The telescopic end of the hydraulic cylinder 46 faces upward and is fixedly connected to the inside of the support frame 41. The first gear 43 and the second gear 44 are always meshed. The support frame 41 is used to support the connecting block 38 at the end of the drum. By setting the bearing 42, the connecting block 38 can be rotated while maintaining the support effect. When the connecting block 38 rotates, it can drive the telescopic inner drum 33 to rotate. Through the snap-fit ​​structure inside the telescopic inner drum 33, the sliding inner core 34 and the main drum body 31 can rotate synchronously with the telescopic inner drum 33. The hydraulic cylinder 46 at the upper end of the sliding support 45 is used to drive the support frame 41 to lift and lower, thereby realizing the transmission and disconnection of power. When the support frame 41 is raised and separated from the sliding support 45, the power is cut off to facilitate the adjustment of the drum length.

[0035] The transmission support unit 4 also includes an auxiliary slide rod 47, a motor support 410, a motor 411, and a gear 412. Two auxiliary slide rods 47 are fixedly connected to the lower end of the support frame 41. The lower ends of the auxiliary slide rods 47 are slidably connected to the inner upper end of the sliding support 45. The motor support 410 is fixedly connected to the outer side of the sliding support 45. The motor 411 is mounted on the upper side of the motor support 410. The output shaft of the motor 411 faces inwards, and a gear 412 is fixedly connected to the end of the output shaft. The auxiliary slide rod 47 prevents the shaft of the hydraulic cylinder 46 from bearing excessive lateral thrust. The motor support 410 is used to mount the motor 411. When the support frame 41 is engaged with the sliding support 45, the gear 412 at the end of the motor 411 meshes with the gear 44, enabling power transmission through the gear set. The motor 411 drives the connecting block 38 and the drum to rotate through the gear set.

[0036] The transmission support unit 4 also includes threaded holes 48 and fixing bolts 49. Two threaded holes 48 are provided at the engagement points of the lower end of the support frame 41 and the upper end of the sliding support 45, and fixing bolts 49 are installed inside the threaded holes 48. When the support frame 41 and the sliding support 45 are engaged, tightening the fixing bolts 49 vertically limits and fixes the shaft of the fixing bolts 49 to the support frame 41 and the sliding support 45, thereby tightly fixing the two separate frames together to ensure the overall structural stability of the frame.

[0037] It also includes a partition block 5 and a limiting slide rod 6. The partition block 5 is fixedly connected to the middle of the inner side of the base 1, and the limiting slide rod 6 is fixedly connected to the inside of the base 1. The left and right ends of the limiting slide rod 6 are slidably connected to the lower ends of the left and right sliding supports 45, respectively. The partition block 5 is used to divide the two sliding supports 45, and the limiting slide rod 6 can limit the two sliding supports 45 inside the base 1, so that they can only slide laterally, thereby allowing the position of the support to be adjusted with the extension and retraction of the drum.

[0038] The working principle of the marine telescopic high-strength drum provided by this utility model is as follows: This drum has a reliable telescopic adjustment unit 3, which can effectively adjust the length of the drum to meet the winding requirements of steel ropes of different lengths. The end baffle 37 is used to lock and limit the steel rope wound on the outside of the drum. When it is necessary to increase the length of the drum, by rotating the wheel 310, the threaded rod 39 can be driven to rotate into the main drum body 31. When the inner end of the threaded rod 39 is against the inner partition 32 on the middle side of the main drum body 31, a reverse thrust can be applied to the connecting block 38. 38 drives the end baffle 37 and the telescopic inner cylinder 33 to slide outward. The telescopic inner cylinders 33 on both sides extend from the ends of the main cylinder 31, thereby increasing the length of the drum and allowing more wire rope to be wound. The locking effect of the locking slide rod 35 and the sliding inner core 34 can prevent the telescopic inner cylinder 33 from rotating, so that it can only slide laterally along the sliding inner core 34. Moreover, the locking slide rods 35 arranged in a circumferential array on the inner wall can provide effective support between the telescopic inner cylinder 33 and the sliding inner core 34, improve the radial load-bearing effect of the drum, and thus effectively ensure the structural strength of the drum. This drum also features a reliable transmission support unit 4, which effectively supports the drum body. The separate design of the upper and lower frames allows for efficient power transmission and disconnection, facilitating drum length adjustment. The bottom frame can move accordingly with changes in drum length, maintaining effective support at all times. The support frame 41 supports the connecting block 38 at the drum end. By incorporating a bearing 42, the connecting block 38 can rotate while maintaining support. Rotation of the connecting block 38 drives the telescopic inner drum 33 to rotate. Through the snap-fit ​​structure inside the telescopic inner drum 33, the sliding inner core 34 and the main drum 31 rotate synchronously with the telescopic inner drum 33. The hydraulic cylinder 46 at the upper end of the sliding support 45 drives the support frame 41 to rise and fall, thus realizing power transmission. The transmission and disconnection are achieved when the support frame 41 is raised and separated from the sliding support 45, cutting off the power to facilitate the adjustment of the drum length. The auxiliary slide rod 47 can prevent the shaft of the hydraulic cylinder 46 from bearing excessive lateral thrust. The motor support 410 is used for the installation of the motor 411. When the support frame 41 is engaged with the sliding support 45, the gear 3 412 and gear 2 44 at the end of the motor 411 mesh, thereby enabling power transmission through the gear set. The motor 411 drives the connecting block 38 and the drum to rotate through the gear set. When the support frame 41 is engaged with the sliding support 45, the fixing bolt 49 is tightened to vertically limit and fix the shaft of the fixing bolt 49 to the support frame 41 and the sliding support 45, thereby tightly fixing the two separate frames together to ensure the overall structural stability of the frame. In addition, the partition block 5 is used to divide the two sliding supports 45, and the limiting slide rod 6 can limit the two sliding supports 45 inside the base 1 so that they can only slide laterally, thereby allowing the support position to be adjusted with the extension and retraction of the drum.

[0039] It is worth noting that the input terminals of the hydraulic cylinder 46 and the electric motor 411 disclosed in the above embodiments are electrically connected to the output terminal of the external power supply through an external control switch group. The control switch group controls the operation of the hydraulic cylinder 46 and the electric motor 411 using methods commonly used in the prior art.
